Description
Technical Field
The invention relates to a ship system, in particular to a green environment-friendly ship gas-liquid energy-saving supply and discharge system.
Background
The energy-saving and environment-friendly requirements for ship use are higher and higher at any time due to the great development of shipping industry. Wherein the emission of ship sulfides becomes an important source of global environmental pollution, and 65% -70% of suspended particulate matters (PM 2.5) and sulfur oxides come from ships. The sulfide is produced by fuel with high sulfur content, and the sulfide in the waste gas can be dissolved in water to form acid rain, so that crops, soil and fresh water resources are destroyed, and the sulfide has great harm to the environment and human health.
In addition, the amount of water discharged by cargo ships during loading and unloading of cargo is different, and ballast water is loaded and discharged during voyage according to the loading state of the ship in order to secure the running safety of the ship. However, when the loading and discharging sites are different, problems of microbial invasion and pollution are caused. Such as when a cargo ship is launched from the open sea and travels to the united states, the microorganisms in the open sea are brought to the united states. With frequent shipments in various countries, the risk is increasing.
And the fuel storage tanks of general ships are heated by the steam generated from the combustion boiler to cool the oil in the oil tanks. The more oil the fuel storage tank is, the longer the fuel boiler is required to generate a large amount of steam. At present, the conventional heavy oil heating mode of the operation ship is to arrange a heating coil in a fuel oil storage cabin, and heat fuel oil in the whole cabin by adopting steam so as to reach the temperature required by lightering. The heating mode has huge steam consumption, and the fuel in the storage cabin exchanges heat with the external environment severely through the cabin wall, so that a large amount of steam is wasted.
